.lle il. known that I, \\'n.i.l \.u. ll.. l\'i.' r;i..\n,a citizen ol' the United States, and a resident. of Columbus, in the county ol` Franklin :ind Stale of (lhio, have invent-ed new' and usel'nl lmprovements in Metallic Ceiling-smi which the following is a iull :ind exact description, reiference being had lo the aew'npnnjfi"g drawings, making parl ol' lhis speeilieatimi.

This invention relates lo improvements in metallic ceilings, and more especially lo the structure for hanging the saine; and il has i'or its objeels lo provide means by which the ceiling may be suspended from a melnllic traine-work, and lo l'orm a structure ai once light and strong.

rlhe description oi lhe ceiling shown in the drawings is contained in a patent granled lo me August 2l, 1888, and numbered 388,285.

The present invention consists in provid.- ing means for hanging this ceiling to metallic structures.

In this class ot' structure the floors Y.are supported usually by th c beams A, v /i'i ich may be of many shapes, according to the structure, as shown in Figs. 9, l0, and 1i of the drawings. Over these beams is laid the door, and

l'rom lhe underside ishung lhehanging-strips ll and el' the invention. 'lho strips 'Il exlend across the room in parallel. lines andare fastened lo the beams A by inea-ns of anyone ofthe devices lll shown in the drawings. In practice I prefer lo use the device shown in Figs. 7 and 8. 'lhe said strips are shaped l'roin sheetiron in the 'form of aehannel, and provided at the open edges with the flanges l), which lie close to the lower edges of the beams A. .lheso-llanges 'may be turned in or ont, so as to extend inlo the grooves E at the sides of the said devices E shown in Figs. T and S. lly means ot' this construction the devices may be shil'led along the length of the si rip, the flanges acting as guides. in the panels shown in ihe drawings lhe lower laces 'ol the channeled strips are Hat; but in some designs of the panels along the .edges l run a raised molding, and in this event the lower faces oli the strips may be provided willi moldings, it' so desired.

'lhe devices ll. of the form shown in l `igs. 7 and 8 are, as stated above, provided with the side grooves lll. 'lhey are also provide-d with the depending' flange E?, which extends loetween the sides of the strips and form therewith guides for the devices. At the 'Forward end the metal ol" the devices is struck up to form the extension E, in shape corresponding with the flange of the beam A, lo which it is to be fitted or placed over. The extension is slighll)v depressed to form a light joint with the llange ot the beam and to draw the strips l to a close contact therewith. rlo strengthen the said extension, the brace E'1 is set in between it and the body of the device. ln the operation of hanging' the said stripsl the devices E are disposed one toI a beam and faced in opposite directions to ihrnst against each other. The strips are thus prepared by sliding the devices E on them and placing them so as to come on the side of the beam desired. VVhcu thus prepared, the strips are raised against the beams A and the devices forced against the beams,with the extensions EE extending over the flanges on the said beam. In this position and for the better security of the stri ps the devices are maintained in position by indent-ing the sides of the grooves E and flanges D when in position, and thereby holding the devices on the strips IOO and pre\'enting them from becomingdetached* from the beams.

The devices shown in Figs. il, 1|),aiid 11. are the same as above described, beingrapplied to different forms of beams A.

In Fig'. 12 of the drawings is shown a method of hanging,r the ceiling wherein I use met-al strips B and C on a wooden structure. rlhis method, renders the work better, as it is lighter, in cases where the strips l5 and C are by design large. In this construction the flanges D of thelstrips are punctured, and screws are driven through the punctures into the wood to sustain them. In this ceilingthe strips C extend between and are supported by the strips'B. They are set apart the dimension of the panel as it extends parallel to the strips B. In this way the strips .l and C, when suspended, form pockets for t-he reeeption of the separate panels of the ceiling. lefore suspending the strips B they are provided at the required intervals with slots eut in the sides. When the first line of the strips ll is suspended, and before the second is pnt in positioin' the cross-strips C are placed between, so that the lugs C', which are formed on the sides of the saidstrips at the ends, are inserted in the slotsformed in the sides of the strips li. As the succeeding,` line ot the strips IS is placed in position, the lugs in the Free ends of the, strips are inserted in the slots in that. strip, and thus held lirmly in position where the latter strip li is secured, and. soon, placing; the si' rips (l in positionbeiween the hanging;I ot' the strips 'Ii until the lop ot' the room is covered with a series of pockets, as shown in Fig', lof d rawings. Atpredetermined intervals the strips li and (l are provided in the channels with serew-threaded perlorations in the lower face. '.two alternative methods et' terminer the pmforations above referred to are. shown at Figs. 5 and t3. ln the one a screw-nut l1 is soldered or otherwise fastened over the peri'orations, while perfor-ations are provided in them inline with the screw-threaded perforations in the hanging-strips. verews are now driven through the panels and engage the threaded perforations in the strips l and (l, and thevhanging of the eeilingis completed.

In some structures, when it is desired to make them more impervious to fire, a fire non -eomlucting material is, poured in on top of this ceiling as a backing'. This, however, I consider in the large majority of cases unnecessary.

1. In a ceiling sueh as described, the hanging structure, consisting in the combinationof the strips li beine' suspended from the beams oi the building structure, the strips (Y, extending' between the said strips B, and suitable connections for suspending the strips CI upon the strips l, substantially as set forth.

2. In a ceiling such as described, the hanging structure, consisting in the combiaton of the strips l, suspended from the beams of the buihlin'gg,` structure and provided at predetermined intervals with slots in the sides, and the strips (1, extending between the strips .l5 and provided upon their ends with lugs C', for being inserted 'in the said slots in the sides of the strips H, to support the strips C, substantially as set forth.

In testimony whereof I have hereunto set my hand this 5th day ot' November, A. I). 1888.
